Definitions

  • the present invention relates to containers with a cap according to the preamble of claim 1, in which the cap can be lightly taken off from a container body with a light operating force by elastic deformation of an elastic ring body. Specifically, the invention relates to an improved technique to increase airtightness inside the container with a cap.
  • the container with the cap is structured from a container body and a cap that is attachable and detachable to and from the container body.
  • the container with a cap there is one in which the cap can be lightly taken off from the container body with a light operating force by elastic deformation of the elastic ring body.
  • the cap forms a part of an exterior of the container and comprises a cap body of a bottomed hollow shape that opens downwards, when the container body is positioned upright, and a ring body fitted inside the cap body.
  • the cap body has an engaging protrusion projecting inwardly from the lower end thereof.
  • the container body is also provided with an engaging projection at an outer surface thereof.
  • the ring body is provided with protrusions on the outer surface thereof which project in opposite directions from each other and are exposed to the outside from holes that penetrate from the inside to the outside of the cap body.
  • the lower end of the ring body comes in contact with the container body, and at least one of the lower end of the ring and a contacting section of the container body with the ring body is made as an inclined surface.
  • the container body has an inclined surface above the engaging projection by gradually reducing in diameter the cylindrical shape of the container body toward the upper end, which becomes an opening of the container body.
  • the cap body When the protrusions of the ring body which are exposed to the outer side of the cap body are pressed, the ring body is urged upwardly while coming in contact with the inclined surface. As a result, the cap body rises and the engaging protrusion of the cap body go over the engaging projection of the container body, and the engagement is released. Namely, the cap can be easily taken off.
  • the cylindrical cap body has a discal sealing section at a ceiling portion thereof to seal an opening of the container body in order to ensure the sealing performance.
  • a tubular plug that is concentric with the disk-like ceiling section is formed by hanging down from the ceiling of the cap body, and an outer diameter of the tubular plug is made to snugly fit to an inner diameter of the opening of the container. Therefore, when the cap is fitted, the outer surface of the tubular plug contacts the inner surface of the opening of the container and seals the container.
  • Patent Literature 1 as the sealing section, it has been proposed to construct such that a plate-shaped packing is provided and the lower surface of the packing comes in contact with the opening end surface of the container body, or a structure that a protrusion is provided to fit into a central opening of the ceiling section to be adaptable to the case where a middle plug is fitted in a central hole in the opening of the container body.
  • the ring body is elastically deformed with the pressing operation of the protrusions, the cap body is made to rise together with the ring body with this elastic deformation, and with this rising force the elastic plug section between the cap body and the container can come off.
  • the fitting degree (strength) of the elastic plug section is set small to a degree that the cap body can be held on the container, so that by pressing the protrusions with a small pressing force, the cap body can come off lightly.
  • the opening of the container could not be sealed in a high sealing state with the cap body.
  • the container with the cap in the background art could not store contents that have high volatility.
  • the airtightness inside the container could not be satisfactorily maintained, and thus such container could not be used.
  • An aspect of the invention to achieve the above object is a container comprising a container body and a cap, the container body having an opening section at upper end thereof to store contents therein, the cap being fitted in a detachable manner to the container body to seal the opening section of the container body, wherein the cap comprises an upper side as a top section, a tubular body section that hangs downward from a peripheral edge of the top section to form a peripheral side wall of the cap, an elastic ring body that is surrounded by the tubular body section and is elastically deformed in a radial direction, and push buttons that are formed on a peripheral surface of the elastic ring body to protrude in opposite directions to each other, wherein at least one of the container body and the elastic ring body is formed with a cone section that gradually expands from the upper side to the lower side, the elastic ring body being moved upward along the cone section when deformed in radial direction to reduce the diameter thereof, wherein the push buttons are exposed from the inside to the outside of the tubular body section, and when the push
  • the container body can be a bottomed hollow shape with a bottom section larger than the opening section, and the cone section can be formed to gradually expand toward a lower side from the opening section to a bottom section. Further, the cone section can be provided to the elastic ring body, and a peripheral side surface of the container body comes in contact with the cone section.
  • the engaging section may comprise a first protruding section provided to the peripheral side surface of the container body, and an engaging piece provided inside of the tubular body section of the cap and arranged to be engaged with the first protruding section, wherein the fitting section is composed of the first protruding section or second protruding section provided to the peripheral side surface of the container body, and a fitting piece provided inside of the elastic ring body to be engaged any of the first or second protruding section.
  • a length that the fitting piece engages the protruding section can be set longer than a length that the engaging piece engages with the protruding section, or a fitting angle between the fitting piece and the protruding section can be set smaller than an engaging angle between the engaging piece and the protruding section.
  • the engaging piece can be formed in a hook-shape at a tip end of a flexible wall section provided to the cap.
  • a plurality of the engaging piece can be provided inside the tubular body section of the cap with a spacing in between in a circumferential direction of the tubular body.
  • the engaging piece can be provided along an entire periphery in the circumferential direction of the inner wall surface of the tubular body section of the cap.
  • the protruding section may comprise the first protrusion that engages with the engaging piece and the second protrusion that engages to the fitting piece.
  • the push buttons can be exposed to the outside via through holes perforated in the tubular body section of the cap.
  • the push buttons can be exposed to the outside via through holes perforated in the tubular body section, and in order to prevent the elastic ring body from deforming in a vertical direction when the cap section rises without pushing the push buttons, a supporting section can be provided to engage the elastic ring body with the cap body section when the cap section rises and thereby to maintain the sealing state of the opening section of the container with the cap.
  • the supporting section can be a brim piece formed on the cap to be engaged with the elastic ring body, or the supporting section can be a brim piece formed on the elastic ring body to be engaged with.
  • this invention can be a container wherein the cap comprises a top plate covered by the top section, adapted to cover the opening section of the container, and arranged inside of the elastic ring body; the tubular body section of the cap surrounds the periphery of the elastic ring body, and includes a supporting section adapted to support a lower end surface of the elastic ring body so that the elastic ring body is always maintained horizontally; the push buttons are exposed to the outside via one of a pair of notched sections and through holes formed facing each other in the tubular body section; and the top plate is formed integrally with the tubular body section via the supporting section.
  • the cap With a container including the supporting section, the cap can be structured from two parts of a first part including the tubular body section having the supporting section and a second part including the top section having the elastic ring body, and these two parts are integrally assembled so that the lower end section of the elastic ring body is positioned above the supporting section.
  • the cap section can be structured from three parts of the tubular body section having the supporting section, the elastic ring body, and the top section, and the elastic ring body is integrally assembled with the cap section such that the ring body contacts the supporting section of the tubular body section.
  • the cap With the container with a cap of this invention, the cap can be easily taken off from the container body by a light operating force, and airtightness inside the container body can be increased, with a structure in which the cap is taken off from the container body by elastic deformation of the elastic ring body as a precondition.
